There are so many variations of issues that may be causing problems in the thyroid, hypothalamus, pituitary, and adrenals that proper testing must always be don.There are a wide range of symptoms of over or under activity of the thyroid and adrenals.
So much of what I was taught as a young doctor, about the HPA axis, and the thyroid and adrenals was wrong. I have had to unlearn much of what I was taught. I was taught that cortisol is a scarey substance that is not safe to use.
If all of the organs of your body got all of the energy all of the time there would not be enough energy to go around. Each organ has its time during the day when it gets the most energy.
Your thyroid symptoms may or may not be caused by problems with your thyroid, but you will never know without proper testing. You are definitely your own best advocate when it comes to your health!!!
